Abstract

The article deals with the problem of quality control of fuel pellets for nuclear reactors. During the development of the control system, various methods for obtaining and processing images of pellet surfaces were investigated. The main difficulty of this task is the imperfect quality of the resulting image of the inspected object, as well as the limited time for its processing. Software and hardware tools and algorithms have been developed for high-performance inspection of fuel pellet geometry, which significantly increase the reliability of inspection results. As a result of the work, stable images with a high degree of repeatability and sufficient resolution have been obtained, suitable for subsequent high-performance, reliable mathematical processing. A high degree of independence of the image and processing results from the individual characteristics of individual products and their batches has been achieved.
